DIE FOR FORMING SPECIFICATION forming part of Letters Patent No. 369,031, dated August 30, 1887.

Application filed Decemberll, 1886. Serial No. 221,252. (No model.)

To all 2071,0771 it may concern.-

Be it known that I, FREEBORN'B. RAYMOND, a citizen of the United States,residing at Rochester, New York, have invented certain Improvements in Dies for Forming Harness- Straps, of which the following is a specificatlon, reference being had to the accompanying drawings.

My invention relates to improvements in [O dies for making certain kinds of harness-straps which require to be slit or divided lengthwise.

My invention is fully described and illustrated in the following specification and accompanying drawings, and the novel features I 5 thereof specified in the claims annexed to the said specification.

In the accompanying drawings, representing my Invention, Figure 1 represents my improved the. Fig. 2 represents a strap of one of the forms which my invention is designed to produce. Fig. 3 is a central longitudinal section on the line or as, Fig. 1. Fig. 4 is a transverse section on the line 3 Fig. 1. Fig. 5 is aside elevation. Fig. 6 is a section on the line y y,

Fig. 1, showing a modification. Fig. .7 is a face view of the follower. Fig. 8 is a section on the line 2 2, Fig. 1.

In the accompanying drawings, A represents the body of my improved die; B, the supporting-block, to which the die is attached; 0 0,

- the knives on the outside of the die, by which the strap is cut of the proper form; and G, the slitting-knife.

In Fig. 2 I have represented a harnessstrap, J, of one of the forms which my improved die is designed to make-such, for instance, as is ordinarily used for the back-strap, which attaches the crupper to the back-band, and which requires to be slit, as indicated at 40 H, Fig. 2, into two parts, I I, adapted to engage with the buckles on the ends of the erupper. The slitting-knife G is inserted in the body of the die in a slot or groove formed therein, being made of a length adapted to the particular kind of divided strap it is desired to make. As indicated in the drawings at N N, the knives G C are bent inward at one end of the body, so as to give the ends I I of the divided strap J the proper form. The knives O O are attached to the sides of the die-body A by means of the screws L. The holesin the knives through which the screws pass are slotted, so as to permit the adjustment of the knives relatively to the face of the body to compensate for the reduction in the width of the knives by grinding, or to adapt the device to cutting leather of different thicknesses. As indicated at O, the sides of the die-block are indented or curved, and the knives C O are bent to a corresponding form,so as to give the required shape to the strap. The surface of the die-block between the knives is provided with suitable curved ribs, P, which project slightly and serve to ornament or emboss the strap, as represented at Q, Fig. 2.

The embossing-ribs 1? may be made of any suitable or preferred shape.

The die-body A is attached to the support I ing-block B by the screws F F. The supporting-block is provided at its center with enlargement E, which receives the plunger D of any suitable press in which it is desired to use my improved die for harness-straps. It will be observed that the ribs P are carried along each side of the slitting-knife G and turned around inside the ends N N, and thence eX- tended along parallel with the straight portions of the knives O C, so as to give the proper finish to the divided ends I I of the strap, as indicated in Fig. 2. 4

In the practical operation of manufacturing harness-straps by means of my invention the die is attached to the reciprocating plunger D of any suitable press operated by hand or power,and the leather from which the straps are to be cut is placed on asuitable table or support underneath the die, which is moved up and down by the press, and at each stroke cuts from the leather a finished strap of the particular form which the die is designed to make.

The straps produced by my improvement are uniform in size and shape, and are produced much cheaper than by the mode ordinarily practiced of manufacturing such'articles.

It is obvious that the slitting-knife may be bent or curved in case it is desired to make a strap with crooked ends. 7

In order to clear the cut strap-from the die,

I provide the follower B, having the emboss- Ic ing-ribs, which slides between the knives G 0, being pressed outward by the springs aa, Figs. 6 and 8. The slitting-knife G is secured to the die-body and projects through a suitable slot in the follower R, as shown in Fig. 6. I secure the follower It to the die-body by the screws 0 c, the heads of which slide in the countersunk holes a c in the upper part of the die-body.

In operation the follower R is forced back by the work before it until it rests against the die-body. As soon as the cut is made and the pressure released,the springs a a force the follower out, ejecting the cut strap.

I claim- 1. The combination, with the body portion and the embossing-die, of the cutting-knives having the vertical slots and the screws passdie, and the latter will also serve to eject the 30 out material, substantially as described.
